Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown in this embodiment, a nut disassembly and assembly device for petroleum machinery includes a housing 1 with an opening on the right side and an internal hexagonal socket 100 disposed on its left side. A square locking block 101 is integrally formed on the right side of the internal hexagonal socket 100. A fixing plate 2 is fixedly connected to the right side of the housing 1, and a U-shaped handle 201 is fixedly connected to the right side of the fixing plate 2. A PLC controller 5 and a warning light 501 are fixedly connected to the bottom right side of the housing 1. A forward / reverse motor 303 is embedded and fixedly mounted on the right side of the fixing plate 2. A torque sensor 302 is fixedly installed on the bottom inner wall of the housing 1, with one end fixedly connected to the output shaft of the forward / reverse motor 303. Both the forward / reverse motor 303 and the torque sensor 302 are electrically connected to the PLC controller 5. A telescopic rotating assembly is fixedly connected to the other end of the torque sensor 302, and the left side of the telescopic rotating assembly extends outward from the housing 1. The magnetic clamp is attached to the square clamp 101. A horizontal drive assembly is fixedly installed on the left side of the fixing plate 2, which is rotatably sleeved on the outside of the telescopic rotating assembly. A second handle is fixedly connected to the bottom left side of the outer shell 1 to facilitate operation. The forward and reverse motor 303 is used to drive the telescopic rotating assembly to rotate through the torque sensor 302. The telescopic rotating assembly is used to drive the inner hexagonal sleeve 100 to rotate during rotation to disassemble and install the nut of the petroleum machinery equipment. The torque sensor 302 is used to detect the rotation torque during rotation and transmit the torque value to the PLC controller 5. The PLC controller 5 is used to control the forward and reverse motor 303 to automatically turn off and control the warning light 501 to turn on for five seconds to clearly indicate to the personnel that the installation is complete when the torque value reaches the preset value. The horizontal drive assembly is used to drive the telescopic rotating assembly to extend and retract laterally according to the installation position depth.

[0023] Specifically, the telescopic rotating assembly includes a square rotating rod 301 fixedly connected to the other end of the torque sensor 302. A rotating shaft 3 is slidably sleeved on the square rotating rod 301. The right end of the rotating shaft 3 has a square sliding hole that slides onto the outer side of the square rotating rod 301, facilitating the left and right sliding of the rotating shaft 3 on the square rotating rod 301. Utilizing the corner-locking characteristic of the square component, the rotating shaft 3 is driven to rotate as a whole by the corner-locking action of the square sliding hole when the square rotating rod 301 rotates. A circular guide sleeve 304 is rotatably fitted on the left inner wall of the outer casing 1. A circular through hole is formed on the left inner wall of the outer casing 1, and a first bearing is fixedly sleeved within the circular through hole. The inner ring of the first bearing is fixedly sleeved onto the outer side of the circular guide sleeve 304, facilitating the rotatable installation of the circular guide sleeve 304. The circular guide sleeve 304 is slidably sleeved on the rotating shaft 3, and the left end of the rotating shaft 3 extends... A square retainer 4 extends out of the outer casing 1 and is fixedly connected. A magnet 401 is fixedly connected to the inner right side of the square retainer 4. The square retainer 401 is movably locked inside the square retainer 4 and attracts the left side of the magnet 401. The square rotating rod 301, rotating shaft 3, square retainer 4 and round guide sleeve 304 are configured to cooperate. When the torque sensor 302 is driven to rotate by the forward and reverse motor 303, it drives the square rotating rod 301 to rotate. The square rotating rod 301 snaps and drives the rotating shaft 3 to rotate. The rotating shaft 3 friction drives the round guide sleeve 304 to rotate. The rotating shaft 3 drives the square retainer 4 to rotate. The square retainer 4 drives the internal hexagonal sleeve 100 to rotate through the square retainer 101 to perform nut installation and removal. The square retainer 4 and the square retainer 101 cooperate with the magnet 401 to form a magnetic snap-fit ​​connection, which facilitates the easy insertion and removal of the internal hexagonal sleeve 100 for nuts of different specifications.

[0024] Furthermore, the transverse drive assembly includes a multi-stage electric actuator 701 fixedly installed on the left side of the fixed plate 2. A movable ring 7, slidably sleeved within the housing 1, is fixedly connected to the left end of the output shaft of the multi-stage electric actuator 701. The movable ring 7 is rotatably sleeved on the rotating shaft 3. A second bearing is fixedly sleeved inside the movable ring 7, and the inner ring of the second bearing is fixedly fitted to the outer side of the rotating shaft 3, thus achieving the effect of rotating the rotating shaft 3. A control switch electrically connected to the multi-stage electric actuator 701 is fixedly installed on the rear side of the housing 1. The multi-stage electric actuator 701 and the movable ring 701 are... With the cooperation of ring 7, the multi-stage electric push rod 701 drives the moving ring 7 to move left and right. The moving ring 7 drives the rotating shaft 3 to slide left and right on the square rotating rod 301. The rotating shaft 3 drives the square retaining sleeve 4 to move left and right, and adjusts the inner hexagonal sleeve 100 laterally. Through the lateral telescopic adjustment, the support length can be flexibly adjusted according to the installation depth. In addition, the telescopic design makes it easy to reduce the extension length later to reduce the overall length, making the size smaller when not in use, convenient to carry and work, and eliminating the need to carry a separate extension rod, thus improving the convenience of use.

[0025] Furthermore, a lithium battery is fixedly installed on the top right side of the outer casing 1. The multi-stage electric push rod 701, the forward and reverse motor 303, the torque sensor 302, the PLC controller 5, and the warning light 501 are all electrically connected to the lithium battery. Lighting lights 6, which are electrically connected to the lithium battery, are fixedly connected to the top left and bottom left sides of the outer casing 1. The lighting lights 6 are used to provide auxiliary lighting when the environment is dark during use.

[0026] The usage method of this embodiment is as follows: When using the nut installation and removal equipment for petroleum machinery, when tightening the nut, move this device to drive the internal hexagonal sleeve 100 to be fitted onto the nut. Use the PLC controller 5 to preset the torque value controlling the forward and reverse motor 303 to turn off and the warning light 501 to turn on, and set the warning light 501 to turn on for five seconds. Start the forward and reverse motor 303 in the forward direction so that it drives the square rotating rod 301 to rotate through the torque sensor 302. The square rotating rod 301 drives the rotating shaft 3 to rotate as a whole through the corner of the square sliding hole. The rotating shaft 3 frictionally drives the round guide sleeve 304 to rotate. The rotating shaft 3 drives the square retaining sleeve 4 to rotate. The square retaining sleeve 4 drives the internal hexagonal sleeve 100 to rotate through the square retaining block 101 to tighten the nut. Torque transmission... Sensor 302 detects the rotational torque applied by the forward and reverse motor 303 and transmits it to the PLC controller 5. When the torque value reaches the preset value, the PLC controller 5 controls the forward and reverse motor 303 to automatically turn off and controls the warning light 501 to turn on for five seconds. This achieves automatic, rapid, and precise torque tightening, and provides a clear indication to personnel during torque tightening, making it easy for them to know the tightening status. Using automatic drive rotation for torque tightening saves time and effort, eliminating the need for manual application of rotational force and improving work efficiency. When disassembling, the forward and reverse motor 303 is started in the reverse direction, which is completely opposite to the direction of movement of the forward and reverse motor 303. At this time, the internal hexagon socket 100 rotates and loosens the nut, thus achieving nut disassembly.

[0027] In addition, the lighting lamp 6 provides auxiliary lighting for the disassembly and assembly work in dim environments. The square clip 4 and square clip block 101, in conjunction with the magnet block 401, form a magnetic snap-fit ​​connection, facilitating easy insertion and removal of the internal hexagonal socket 100 for nuts of different sizes. When the nut installation position is deep and requires increased length, the forward-starting multi-stage electric push rod 701 drives the moving ring 7 to move to the left. The moving ring 7 drives the rotating shaft 3 to slide to the left on the square rotating rod 301. The rotating shaft 3 slides to the left within the round guide sleeve 304, and simultaneously... 3 drives the square sleeve 4 to move to the left, and the square sleeve 4 drives the internal hexagonal sleeve 100 to move to the left to adjust, thereby increasing the adjustment extension length. When the length needs to be shortened after subsequent use, the multi-stage electric push rod 701 is activated in the reverse direction, causing it to drive the rotating shaft 3 to move back to the right and retract into the outer shell 1 through the moving ring 7. Through the lateral telescopic adjustment method, the support length can be flexibly adjusted according to the installation depth and the length can be reduced when not in use. There is no need to equip a separate extension rod, which facilitates the integrated telescopic adjustment application and improves the ease of use and carrying.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
